Every year March 4 marks World Obesity Day, a reminder that weight is far more than a number on the scales. For decades, society blamed laziness and indulgence. Today, science tells us something profoundly different: obesity is a complex, chronic disease affecting over a billion people globally.

“Weight gain is not an isolated issue,” said Dr Pooja U.K., Consultant Endocrinologist, Prakriya Hospitals, Bangalore. “It is the thread connecting multiple health problems, from diabetes to joint pain,” she added. Obesity, she informs, triggers inflammation, hormonal disruptions, and more than 230 medical complications, making it a major threat to quality of life.

According to Dr Pooja, lifestyle changes remain the core of good health. “Balanced nutrition, sleep, exercise, and stress management,” she said, adding, “However, for many, these efforts alone aren’t enough. This is where medical science steps in, offering transformative therapies.”

GLP-1 analogues

GLP-1 analogues like semaglutide and tirzepatide mirror gut hormones to regulate appetite, insulin, and satiety. Clinical trials, the doctor says, show remarkable results, where patients can achieve 14–20% weight loss, alongside better blood sugar control.

Dr Pooja emphasised, “For someone struggling to reduce insulin doses, or with knee pain limiting movement, these drugs are life-changing. They’re not cosmetic shortcuts; they restore health and mobility.” Emerging triple agonists like retatrutide show even more promise, with nearly 29% weight reduction in studies, alongside improved metabolic markers.

Understanding risk factors

Explaining why expert guidance matters, she explained, “These medications are powerful prescription therapies, not over-the-counter supplements.” Before starting, a full medical assessment is essential.

“We evaluate risk factors, comorbidities, and long-term goals. Not every patient is a candidate,” shared Dr Pooja. “Monitoring is crucial to ensure safety and efficacy. Experimental trends such as 'microdosing' or buying unverified compounds are risky. Precision matters when hormones and metabolism are involved,” she added.

Obesity rarely exists alone; it often coincides with diabetes, thyroid issues, heart disease, or kidney problems. Endocrinologists work alongside dietitians, cardiologists, and nephrologists to personalise treatment.

“Managing obesity today is about preventing heart attacks, protecting kidneys, preserving mobility, and extending healthy years of life,” said Dr Pooja. Combining lifestyle foundations with GLP-1 analogues or newer agents represents a medical partnership, not an instant remedy.
